The slopes of perpendicular lines have a product of -1.

anonymous · Answer

the multiplication of slopes is $-1$ if lines are perpendicular to each other

so $m_1 \times m_2 = -1$

you have $m_1 = -\dfrac{1}{4}$. plug in that and solve for $m_2$

anonymous · Answer

@micahwood50 im honestly confused on these problems so are you saying it would be -1/4 x -1/4

anonymous · Answer

no, i mean product of two slopes from lines that are perpendicular to each other is always -1

And you know that one of slope is -1/4

So you have $-\dfrac{1}{4}m_2 = -1$

solve for m2, it will tell you the slope of other line

anonymous · Answer

am i clear? no?

anonymous · Answer

@micahwood50 no dont get it how would i get the slope for red one i know green slope is -1/4 but how would i get the red slope

anonymous · Answer

or how do i solve for m2

mathstudent55 · Answer

The product of the slopes of perpendicular lines is -1.
This is the same as to say:
The slopes of perpendicular lines are negative reciprocals.
That means if you know the slope of a line, to find the slope of a perpendicular, write teh slope as a fraction, flip the fraction and change the sign.

anonymous · Answer

so it would be 4?
